I was hoping someone could shed some light with some good
links, sample configurations, etc., that might help me
with the following. Not looking for someone to "fix it"
for me or anything like that. Maybe the following will show
that I have tried reading, googling, experimenting, etc.,
before asking. I don't want to have any settings too high
to cause other problems, just to change what's neccessary.
When I'd drag & drop files to copy from a windows xp box
to an nfs share on the obsd box, the obsd system would
reboot. I thought at first that it was either something
conflicting from the xp box, or that I had a hardware
problem on the obsd box. That had happened once with a
bad simm, but I had replaced it & had had no further
problems until now. Before running a time consuming
memory test on the obsd box, I did some reading on obsd
tunables, and am now able to copy a file over from the
xp box without the system rebooting. Below is a list of
the changes:
net.inet.tcp.keepinittime=600
net.inet.tcp.keepidle=28800
net.inet.tcp.keepintvl=600
net.inet.tcp.recvspace=65536 net.inet.tcp.sendspace=32768
net.inet.udp.recvspace=83200 net.bpf.bufsize=65536 vfs.nfs.iothreads=4
What type of nfs mount are you using? v2 or v3; udp or tcp?
Any info on the console the moment the machine reboots? What is the
value of tyhe ddb.panic sysctl? Anything in the logs?
-Otto
Looks like v3, tcp. there was nothing on the screen when the
box rebooted. Just goes blank & reboots. Looked through the
logs & couldn't find anything, either. Running sysctl -a | grep ddb.panic
returns `ddb.panic=1'. I'm a relative newbie, so I could be completely
offbase, but this doesn't look good. Looks like maybe it could be a
hardware problem. Maybe the settings I upped could are just taking some
of the strain off the system. I read in the obsd faqs, concerning nfs,
that nfs filesystems should be mounted with 0 0 on the end of the line
in /etc/fstab so the computer doesn't try to fsck the nfs filesystem on
boot. Here's what my /etc/fstab looks like & /etc/exports:
/dev/wd0a / ffs rw 1 1
/dev/wd0h /data ffs rw,nodev,nosuid 1 2
/dev/wd0f /home ffs rw,nodev,nosuid 1 2
/dev/wd0g /tmp ffs rw,nodev,nosuid 1 2
/dev/wd0e /usr ffs rw,nodev 1 2

I don't quite understand the faqs I read, I guess. I thought
all you had to do was put the right parameters into /etc/exports
and you were good to go. Not having any problems on the old
hp netserver running fbsd_5_4. Hope some of this helps. Hurried
gathering the info. Have head off for work shortly.

Before the problem started occurring, I was using softupdates. I tried running
without them, thinking maybe that had some bearing on
the problem. Apparently it didn't. The only thing that helped was the
changes listed above. I read that if you increase the tcp.recvspace &
tcp.sendspace too high, you can cause a kernel panic when booting.
That hasn't happened so far, with the above values. Exactly how high
I can go without problems, I don't know. The obsd box is used for email
& learning, mostly. No high usage production server. The largest file
I've tried to copy to the nfs share since making the changes was about
26mb. No reboot this time. Before the changes, about the largest I could
copy without trouble was 2mb. Right now, I'm limited on memory. There's
only 256mb on the obsd box. That might be a problem, too, if I keep
increasing the above values. There is no problem with file sizes when
using scp across the network. Forgot to mention that I had tested it
too, by mounting an obsd nfs share over on a fbsd box & had tried to
copy a large file over, resulting in a reboot. That was when I figured
I had it narrowed down to hardware or an obsd settings problem, the
latter apparently being the case. Thanks for any answers & advice.
